Remove Thrift, improve makefile, and update version

This pull request should fix the botched 0.05 version change I did. It also moves the test files that require a live cassandra server to a different folder. These tests are no longer part of the default tests.  Another change is the removal of the embedded Thrift module. The 0.8.0 version of Thrift which was embedded is now available on CPAN. Also, a newer version of Thrift, 0.9.0, is available on CPAN.
